Tosallwhom-tmay concern Be itknownthat I, JOHN MACLAURIN, a citizen of Great Britain, residing Vatlvroolfield;` inthe county. of Worcester.r and State off Massachusetts, have invented.i certain new anduseful Improvements in. Hand Sea-ling- Machines; and I doihereby declare thev following tofbea ulLclear, and; eXact descrip.- tion of the invention, such as will enable others skilled in the art to which. it .appertainst'o make7 ande use'the same.

rEhis invention relates to sealing machines and more particularly tofhand machines.

ltlhaslfor an object toprovide a.: machine of lthis classswhich. may be easily operated by' a single. handl and may he tilted to any positionvr necessary for the application' of sealing'tape withoutzspillingtheliquidfrom the7 reservoir;

A. further object of' thisV invention isa provision of a. moistening roller which is normally disposedout .of contact-withsthe p sealingtape so thatthe gummedi surface or theagumming liquid which may be applied to-.tlietapel is not in contact with they moistening surface or adhesive applying surface.

A further object ofthisinventionisa pro- .visionfof an improved? meansffor manipulating aneY improved form of cuttingrknife.

Furtherqohj ects wille'heappar'ent from .the followingspecification, appended claimsand drawings: inf which,

Figure 1r is .a vertical :sectional view throughl the. device embodying., the features off this invention, Fig 2 isa plan. view of the machine, Fig.` 3 isi a vertical cross 'sectional' view as on the line 31e-3 of Fig.y 1j, Fig. 4; is asimilar view asfon: thefline 4-.4 ofllig.V 1', andFig. 51is a bottom view.^

In a device of this character, it is desired to/have a compa'ctmachine which may be easily operatedlv` a single hand, o'fanfo'pen atorandztohave certain parts thereof so arranged that upon the removal; of the operators` hand, these parts resume a normalposition.. f

.Referring to the drawings. showingthe elements of this invention, 10 indicates. a :frame comprising a hollowy wall in which liquid may be placedin the chamber- 112. The side walls-off the fra-meare connected by .a trough. 121 in which: the; liquid :fromthe 'chamber 11 may freely passxandzthisftrongh iszadaptedftovrceive a moistening roller 1-3 which. may beofanydesired material; such as. brass or its. equivalent, This rolleris adapted to fbefswung-about av pivot 1'4" asby a. yoke 15: which supports journals-for a shaftv 16a and;` tov which. one; end of' al link;Y 1.7 ispivotally connected; asyat 18.- TheA oppositeendi of the linkf 17 ispivotally connected tio alever .1!9 :as at 20zand this lever. is-connectedY to a handle 21 as at; 22; When vthe openatois hand .grips the handle 21, 'the fingers. include the lever-1f9 at which time the roller `13f moves.

ByY this train of gears, the roller 32 moves in unison with the roller 25 and the roller 32.'.is1sorpositi'onedas. tor-receive pressure exertedA .by the roller 183 pressing against the tape 23g-'to assure the.ipropenapplicationg orV knife may be brought into contact With thetape as it passes the roller 25. The lever 29 extends above the pivot and has its upper end connected as by a link 41 to one end of a handle 42 which is pivoted as at 43 to the handle 2l. The handle 42 is returned to'norymal position as by a spring 44.

, Inv use, the tape is threaded through the machine as shown and When it is desired to apply a portion thereof to a package 0r the like, the lever 19 is raised to raise the roller 13 to apply liquid to said tape before it passes about the roller 25. The handle is held in raised position and the application of the tape may be continuous until the desired amount has been applied, after which the handle 42 may be depressed when the spiral knife 36 --may sever the tape as is obvious. In applying the tape to a package, it is frequently desired to tilt themachine to Contact with the vertical sides of the package at Which time, the liquid vvillfiow from the trough l2 into'the chamber 1l in any position of the machine so. that the throat of the trough 12Will not form an outlet for any of theliquid except as applied bythe roller 13 when the machine is in horizontal position. Furthermore, the knife 36 cuts the tape at anangle to aiforda reduced i end on both ends of the tape so that the reduced end of the section of the tape applied to an article4 affords a moreperfect application of the tape, While thereducedy end remaining in; the machine .affords a guide to direct the tape for further application. i

Various modifications maybe made With respect to the several parts including the proportionsand relative positions of the several parts, Withoutldeparting from` the spirit of the invention and it is thought that the operation of the device is clear in view .of the foregoing.
